4 Claims

1. Pellets, comprising:

an acrylic block copolymer (I) comprising a polymer block (A1) comprising methacrylic acid ester units and a polymer block (B1) comprising acrylic acid ester units, and

an acrylic polymer (II) comprising 35 mass % or more methyl methacrylate units and having a melt flow rate (MFR) measured at 230° C. under 3.8 kg load of not less than 10 g/10 min,

wherein

the acrylic acid ester units present in the polymer block (B1) of the acrylic block copolymer (I) consist of methyl acrylate units and acrylic acid ester units of formula CH₂═CH—COOR¹(1), wherein R₁represents a C4-C12 alkyl group,

and

a mass ratio (I)/(II) of the acrylic block copolymer (I) to the acrylic polymer (II) is from 90/10 to 40/60.
